Updates pycryptodome from 3.23.0 to 3.24.0

Release notes

Sourced from pycryptodome's releases.

v3.24.0 - Evreux

New features

• Speed up KangarooTwelve by 50% for long messages (1MB or more).
• New parameter threads for Crypto.Hash.KangarooTwelve.new(), to hash long messages on several CPU cores (threads=0 for all of them). The output does not depend on the number of threads.

Resolved issues

• GH#875: Fixed the Object Identifiers (OID) for BLAKE2.
• Fixed a potential DOS attack when decrypting a password-encrypted PKCS#8 key, when the iteration count is enourmous. Decryption will now fail if it exceeds 50M iterations; the limit can be changed or removed via the new max_iteration_count option. Thanks to afldl for reporting.
• Fixed the maximum number of bytes that GCM should encrypt. Thanks to Loganaden Velvindron.
• Fixed ECC operations on 32-bit Windows (x86) wheels: due to a compiler bug in Visual Studio 2022, the modular inversion skipped half of the exponent bits, producing wrong results.
• Fixed a bug in KangarooTwelve in the scenario where customization string is very long (8190 bytes or longer) and the message to hash is empty.

Other changes

• Build Windows wheel with Visual Studio 2022, from Visual Studio 2019.
• Remove support for Python 3.7.

Updates ruff from 0.16.8 to 0.17.0

Release notes

Sourced from ruff's releases.

0.17.0

Release Notes

Released on 2026-10-09.

The executables in our macOS and Windows release archives and ruff wheels are now code-signed. macOS executables are signed with an Apple Developer ID certificate and notarized by Apple. Windows executables have timestamped Authenticode signatures from Azure Artifact Signing. This enables verification of the release publisher and binary integrity, supports publisher-based allowlisting, and should reduce security warnings and antivirus false positives.

Breaking changes

• Update the default and latest Python versions for 3.15 (#28792)

  Ruff now defaults to Python 3.11 instead of 3.10 when no Python version is configured through target-version or requires-python. When checking for syntax errors without a configured Python version, Ruff now defaults to Python 3.15 instead of 3.14.

• Update the default rule set (#28786)

  Several of the flake8-datetimez rules (DTZ001, DTZ005, DTZ006, DTZ007, DTZ011, DTZ012, and DTZ901) are no longer enabled by default, while undefined-local-with-nested-import-star-usage (F406), which corresponds to a syntax error, is now enabled by default.

• Update Rust crate quick-junit to 0.8.0 (#27295)

  JUnit output now uses a skipped attribute instead of disabled on <testsuite> elements and includes a skipped attribute on the root <testsuites> element.

• [flake8-import-conventions] Add datetime as dt as a conventional alias (ICN001) (#28790)

• Support Unicode dummy variable names (#28722)

  The default lint.dummy-variable-rgx now recognizes underscore-prefixed Unicode names, such as _次, as dummy variables.

• Update to Unicode 17 (#21229, #28784)

  Ruff now uses Unicode 17 data for identifier normalization and named character escapes ("\N{...}").

• Always show unsafe and display-only fixes in the CLI (#27810)

  The default full output format now shows unsafe fixes and suggestions requiring manual review, regardless of the unsafe-fixes setting. Actually applying unsafe fixes still requires explicit opt-in.

• Remove the Python dependency from conda-forge builds (conda-forge/ruff-feedstock#361)

  The conda-forge build no longer depends on Python, now supports linux-riscv64, win-arm64, and linux-ppc64le platforms, and now includes shell completions. However, no longer depending on Python means that python -m ruff and import ruff will no longer work. Use ruff directly from PATH instead. PyPI installations and those from the standalone installer are unaffected.

• Remove support for ruff-lsp (#28750)

  Support for ruff-lsp, the legacy Python language server deprecated in Ruff v0.9.5, has been removed. The Ruff VS Code extension now always uses the native language server; ruff.nativeServer is deprecated and ignored. See the migration guide.

Stabilization

The following rules have been stabilized and are no longer in preview:

• lazy-import-mismatch (TID254)
• lazy-import-immediately-resolved (TID255)
• os-path-commonprefix (RUF071)

... (truncated)
